Estimate
Requirements Comments
Equipment          
Collimators - 1 6 months distributed over 2 years Sophisticated high level application for manual control. Automatic optimisation of jaw positions - dedicated RT task - lower priority initially Functional Specification in progress. First prototype in place for SPS tests.
TDI / TCDQ 1 1 2 months - prototype for collimators Movable - aim for incorporation in collimator application As for collimators
Beam dump - 1 2 months - this has got to be good Dedicated Application
Tests, diagnostics, post-mortem, status
 
Power converters 1 1 Extenstion of existing for HWC Individual PC diagnostics. Full control from equip state. Global set send. HWC. Will be fully integrated into operational sequence
RF - 1  4 months RF feedback response (longitudinal and transverse)
Frequency modulation,
Settings, state control, diagnostics
Needs requirement spec
Transverse feedback - 2 3 months Dedicated application. PM. Diagnostics. Functional specification required
Kicker 1 1 2 months Analogue acq. etc.. automatic & manual, Kicker voltage and timing adjustment (plus usual trim/archive functionality)  
Septa 1 1  - Treat as standard power converter - usual trim functionality. Monitoring.  
Warm magnets - 1  - Standard power converter facilities Treated like the rest for the most part.
Spectrometer & compensation - 2  1 months Should be standard trim and settings functionality. fixed display for status.
